Why would you want to root for MU to win on Saturday? Do not believe the talk about us needing MU to win in order for KU to go to a BCS BOWL, it is false. There are plenty of scenarios that could play out in order for KU to still make it to a Fiesta Bowl.
Cheering for your rival to win the National Title or even the Big 12 title doesn't make any sense at all.
